Mario Kart DS Probs

I`m still having trouble conneting to the internet with my Wanadoo LiveBox with Mario Kart DS. Without sounding like a complete pillock could someone please explain in detail how exactly you set up a manual connetion with it. I do not know what half the terms even mean.

Really need to get this going and I know that others use a Livebox succesfully.

Please help before I go mad ;)

Jason.
